Inspired by the linked XKCD. Using 60% instead of 50% because that's an easy filter to apply on rottentomatoes.
I'll go first: I think "Sherlock Holmes: A game of Shadows" was awesome, from the plot to the characters ,and especially how they used screen-play to highlight how Sherlocks head works in these absurd ways.
Solo (Star Wars) comes close at 69%. It was absolutely a story that didn't need to be told and I really didn't like them trying to explain everything like, "Here's how Han got his trusty gun, here's how Han got the name "Han Solo", here's how..." blah blah blah, like I really didn't need any of that stuff, BUT I actually liked the movie regardless. It was a low-stakes movie that barely had a hint of any Sith or Jedi, it was just underworld business people doing underworld business things, it was great. Young Harrison Ford was always going to be a huge stretch for anyone, but I thought Alden Ehrenreich carried it well, and Paul Bettany was awesome in his role.
Also, Primer only having a 73% is a goddamn travesty.
Because I like Star Wars and sometimes I imagine I'll get surprised or that my first impressions won't be true. Solo fits that bill, it was something that was surprisingly good. Recently Andor was just as surprising if not more. I went into Andor thinking I was going to absolutely hate it and even quit on it two episodes in (Disney+ shows have had a bad track record so far), then went back in and was blown away. Just because I'm expecting something to be bad doesn't mean that's how it will turn out.
